Шачи

Shachi is the son of the pirate Akashachi. Shachi was left behind in Asura after Akashachi fled during an attack and there he became romantically involved with Leia, a local girl. One day he encountered an enemy where he then was saved by Jukei. Jukei noticing his skills, took him in as his fourth student and thought him Hokuto Ryuuken, which Shachi used to to protect Leia. He began fighting against the Asuras, eventually earning a reputation as "Rakshasa".

At first, he only teams up with Ken to use him in his plot to destroy the three "Rashou", allowing Lin to be captured by Kaioh so that Ken would fight him.
